Specification of Letters Patent.

Patented March-12, 1907.

Application filed November 19, 1906. Serial No. 344,094.

To all whom it may concern:

Be it known that we, EUGENE D. C. BAYNE and LAwnENoE A. SUBERS, citizens of the United States, and residents of Cleveland, county of Cuyahoga, State of Ohio, have invented certain new and useful Improvements in Automobile-Tire-VVinding Machines, of which we hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in] similar to that of the tire and upon which the circumferentially-laid thread is wound; also instrumentalities for applying the thread closely to the wheel-surface as the tire-frame is rotated upon its axis, and automaticallyoperating mechanism for feeding the thread in closely-approximated rows upon the tireframe surface, so that the several strands shall adhere together and form a uniform. coating or layer thereon.

Furthermore, the machine is designed for use in winding the form of tire described in an accompanying application for apatent, in which a layer of transversely-laid thread is alternated with a layer of circumferentiallywound thread, and each thread is enveloped in a tube or solid coating of insulating and preferably vulcanizable material, which at the time of winding has an adhesive surface, so that as the threads are successively wound upon the surface of the tire-frame they will adhere together and the completed fabric or tire will form'an integral or unit ary structure, and when vulcanized a perfect vendible tire of heretofore unattainable strength and resistance to circumferential and transverse stresses is thus obtained.

The invention also comprises the detachable, collapsible, and highly-polished metallic tire-frame, the various instrumentalities for guiding and feeding the thread, and

means for automatically adjusting the positions of the thread guiding and applying instrumentalities, and the various means for preparing and feeding the prepared thread to the machine and the combination and arrangement of the various parts and cons truction of details, as hereinafter described, shown in the accompanying drawings, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of the device, showing the rotatable tire-frame, its support, and the positions of the various thread-guiding and thread-applying devices and the means for preparing the thread. Fig. 2 is a side elevation thereof. Fig. 3 is .a plan view thereof. I ig. 4 is an enlarged sectional View showing the upper part of Fig. 1. larged view of the upper part of Fig. 2. Fig. 6 is a transverse section of tire-frame on center line, showing the thread-laying rollers or director-wheels which apply the thread to the laterally -extending flange of the tire-frame, which corresponds to the clencher portion of the tire. ll igs. 7 and 8 are detail views in plan and elevation of one of the director-wheels, by means of which it is applied to its exact position upon the tire-frame. higs. 9 and 10 are similar views of one of the thread-guiding wheels. Fig. 11 is an enlarged detail of one of the director-wheel holders, by means of which the sides of the tire are wound. Fig.

-12 is a similar view of the balanced holder for the thread surface of the tire. figs. 13 and 14 are detail views of the receptacles, drawtubes, and air-passages through which the cord passes to the machine in its insulated form.

In the fi ures, 1 is a detachable, collapsible, and highly-polished metallic tire-frame upon which the threads forming the tire casing or tube are wound. This tire-frame is divisible into four sectional parts attached together by means of the bolts 2, passing through flanges 3, so that the completed tire casing or tube can readily be removed. This sectional tire-frame is mounted upon the periphery of the wheel-rim 4:, which is supported by means of arms 5 and hub 6 upon a driving-shaft 7, mounted in bearings 8 on a suitable frame 9. The rim is made expansible to securely clamp the tire-frame thereon by means of the slotted opening 10 therethrough and a connecting or expanding bolt or bolts Fig. 5 is an en 1.1, by means of which the edges of the slot can be forced apart, and thus employ frictional contact under pressure to retain the tire-frame in position.

In order to make the removal of the tire frame convenient, the shaft upon which the wheel-hub 6 is mounted is divided. within the hub or adjacent thereto, as at 12, and the outer bearings 13 and frame 14 are slidably mounted. upon guides, such as the rods 15,

upon the common bed-plate 16, so that the outer bearings and outer portion of the shaft can be moved to permit of the removal of the tirecasing or tube.

Means for rotating the tire-frame are shown, as cranks 17, upon each end of the shaft; but we do not limit ourselves to the identical forms of construction of this or other portions of the machine, since other equivalent means can be employed to obtain the desired results and lie within the spirit of the invention.

The two portions of the shaft rotate in common, and a tongue upon one portion is shown entering a groove in the other portion with this object in view.

Upon each side of the vertical center of the tire-frame are shown the directonwheels 1t) 19, over which the prepared insulated threads A, having a perfectly cylindrical and compressed surface, are designed to run, and which apply the threads directly to the surface of the tire-frame upon the sides thereof, commencing at the inner edge or angle and build the thread A in a constantly-he creasing spiral wind. with the incasing insulation of each row of threads in contact until a position is reached at 21 at approximately an angle of thirty degrees to the axis of the tire-frame. These threads being incased in adhesive material immediately adhere to gether and to the transversely-laid layer 22 of similar thread below and retain their posi tion without difficulty, and being of perfect shape and having a carefully-adjusted regular upward movement fit immediately into their places without possible distortion or danger of overlapping of the separate strands.

The upward movement of the winding or director wheels is automatically accomplished, and this movement and the means for obtaining such slight lateral movements under control as may be necessitated. by the flaring or out of vertical shape of the tireframe sides may be described as follows: The director-wheels are pivotally mounted within the forks 23, which pass through squared openings in the supports 25. The fork-stems are also angular, so as not to retate in. these openings. These supports are vertically movable upon guide-rods 27 27 fixed in the platforms 28 28, which are mounted upon the frame portions 9 and 14.

The supports for the director-forks and director-wheels are slowly raised to correspend to the diametrical increase in the size of the spiral winds by means of the right and left screw-threaded vertical shafts 2t) 2%), which pass through corresponding nuts 30 in the supports, and these shafts are rotated in conjunction with the shaft by means of the connecting bevel-gears 81 and 32 and the movements are accurately prqmrtioned and the pitch of the screw so regulated as to raise the platforms 28 2S and the director-wheels 19 19 carrying the thread upon the periplrerr of the tire-frame exactly one diameter of the thread at each revolution of the tire-frame.

The forks can be set to limit their inward travel by means of sonny-threads 33 upon their outer ends and nuts 34 engaging their supports. Springs 35, connecting the forks and supports, force the director wheels into constant contact with the tire-frame. so that the thread is directly applied thereon and cannot get out of position and also provide sufficient elasticity to permit of lateral movement to the required degree. Guide wheels 35 serve to direct the thread to the director-wheels.

Clutch levers and rings ("10 and t5] engage the bevelgears 32 on. the shaft 7 and throw the gears to stop the action of the right and left hand screws 29 29 as soon as the threads have been wound sufficiently high on the tire-frame to permit the winding of the erown portion thereof, and the director-wheels nieel closely and the thread is moved from one to the other by hand.

As soon as the sides of the tire-fran'ie are wound full up to the angle suggested. other director-wheels 36, arranged to engage each side of the center of the crown on the treadsurface of the tire-frame, are employed to continue the winding of the threads to the (iliametrical central plane of the tire-frame. These wheels are mounted upon a horizontal rod 37, upon which they are free to more laterally, and this rod is mounted in a wide fork 38, which is adjustably supported for vertical movement in the head 39 by means of spring-pressed rods R. The head is attached to the standard 40 by means of a pivot 41, which enables the head and attached fork and director-wheels to be lifted while removing the tire casing or tube.

It will be seen that as one thread is laid after the other the director-wheels 36 will readily move toward each other until they completely fill the tread on the crown portion of the tireframe-that is, the grooves in the director-wheels 36 follow the insulated threads as they are laid, and hence the wheels move toward each other as the rows of thread increase in number until the flat sides of the two director-Wheels engage at the center of the crown.

Guide-wheels 42 42 are employed, to guide the threads to the director-wheels, and since they must move with the directonwheels each guide-wheel is mounted in an arm 44;, attached to a central hub 43, which is in turn provided with a semicircular flange and groove 48, which is engaged by an annular flange 49 upon the hub of the director-wheel, so that the director-wheel will move the guide-wheel arm as it travels. T o prevent the guide-wheel from tipping, a second arm 46 is provided with a roller 45, which runs upon a horizontal rod 47, mounted upon the fork 38.

The highest path of each side-Winding director-wheel and the lowest path of each crown director-wheel come so closely together that the thread will almost run from one to the other. However, the thread is placed in position in the proper guide when the exact position of transfer is attained and the machine is not necessarily stopped to permit this transfer if run slowly.

The devices for winding the thread upon the lateral extension E of the tire-frame are seen to be operated simultaneously on each side thereof and comprise director-wheels 50, pivoted in spring-controlled forks 51, which move longitudinally in supports 52 and the stems 53 are squared to prevent them from turning. Upon these supports are also rigid forks 54-, in which are pivoted the guidewheels 55, by means of which the threads are brought to the director-wheels. These supports 52 are pivoted for lateral swinging movement upon the arms 56, which are attached to the same standard which supports the director-wheels 36 36 above. One of these arms is hinged at 57 so that it can be turned away from the tire-frame when the tire casing or tube is to be removed.

The director-wheels first place the thread in the innermost angle at 20, and thence the pressure of the adjacent thread will cause the directors to lay the thread smoothly in outwardly-widening circles until the edge is reached.

Since the groove in each director-wheel will follow the insulated thread as it is laid and as the rows of thread extend farther from the center of the frame, the directorwheels follow the Widening circles and the springs maintain an elastic pressure of the director-wheels upon the threads. The springs 35 readily permit of this action.

An essential portion of the device is found in the instrumentalities for coating the thread with the tubular insulation, since the thread thus coated is too sticky to be wound upon spools or spindles and must come directly from the bath and formers to the tireframe. This device is specifically represented in Figs. 13 and 14 and comprises a se ries of receptacles, such as P and P, filled with a solution of insulating material, such as rubber, through which the thread passes. Each receptacle is provided with a vertically through which the thread passes. The tubes are graduated in size, and after the thread has received its first coating in the upper tube it passes through a box or conduit C, through which a drying-current of air passes, and when thoroughly dried the thread passes through the lower receptacle P and through second tube T of slightly larger diameter than the first tubes T, which increase the thickness of the coating materially. A second drying-current of air is passed through the conduit C, then dries the coating thoroughly, although the sticky surface is still retained. The tubular coating upon the thread is then molded and compressed into a perfect cylindrical form while still plastic and by means of rollers S and S, which are designed to draw the thread centrally through the tubes at a, speed equaling the speed of the machine, so that the thread will not be under any undue tension when applied to the tireframe. In this manner a perfect tire-casing or tube can be wound with circumferential and transverse layers of thread, which are not at any time in direct contact,

each other. The layers of transverse thread can be introduced at any time most convenient in the course of the winding. The transverse layers of thread can be introduced by hand upon the tire-frame in the path of the winders, so that one continuous action will wind the complete wheel.

We believe ourselves to be the first to wind a pneumatic tire-case and inner tube with threads in a circumferential manner by means of a collapsible circular frame and automatically-operating mechanism adapted to apply the thread thereto and also to apply a thread having a tenacious surface thereto or to a tenacious coating thereon under elastic pressure. It will be observed that while the springs upon the directorguides serve to permit of lateral and vertical movement under control of the threads they also provide a continuous pressure thereto, I which forces the threads into their exact po- 5 sition relative to each other and assists in i producing a regular and even wind, as well i mate contact, so that their contacting surfaces will adhere elosely together.
